How much do solar panels cost?
The average cost of solar panels in the US is $3.20 per watt installed. A typical 7kW residential system costs approximately $22,400 before incentives. Prices range from $2.60/W in Oklahoma to $4.20/W in Hawaii, with most states falling between $2.70 and $3.60 per watt.
What is the solar payback period?
The average solar payback period in the US is 8-12 years, depending on your location, system size, and local utility rates. States with high electricity rates and good sun exposure (like California and Arizona) have payback periods as short as 6-8 years. After payback, the system generates free electricity for the remaining 15-20+ years of its lifespan.
How many solar panels do I need?
The average US home needs a 6-8kW solar system (15-20 panels). The exact number depends on your electricity usage, available roof space, local sun hours, and panel efficiency. In sunnier states like Arizona, you may need fewer panels; in northern states, you may need more.
